Stainless steel | 1.4521 | AISI 444

The ferritic stainless steel 1.4521 impresses with its excellent corrosion resistance, particularly to chloride-containing media, as well as its good oxidation resistance at elevated temperatures. Thanks to stabilization with titanium and niobium, it offers high resistance to intercrystalline corrosion and stress corrosion cracking, making it ideal for use in the automotive industry, plant engineering and the chemical industry. 1.4521 is used particularly in exhaust systems, heat exchangers and tanks due to its durability and weldability. Metal 3D printing using laser powder bed fusion allows complex and corrosion-resistant components to be manufactured from 1.4521 efficiently and in a resource-saving manner.
